The Voices of the ElePHPant podcast has released their latest episode, an interview with Keith Casey, a developer evangelist at Twilio.

Cal's "three questions" for Keith revolve around his work with REST and how it relates to the Twilio API:

• What new technology do you see up and coming that will effect PHP developers the most?
• What's the most important part of REST that PHP or other developers aren't getting?
• What's one feature that developers don't know enough about in the Twilio API that you think they should?
• Bonus Question: Some information about HubAustin
